Nasal Assimilation and Pronunciations of Korean Consonants

When you say thank you (감사합니다) in Korean, you say gam-sa-ham-ni-da. You do not say gam-sa-hab-ni-da, due to nasal assimilation.

Nasal assimilation, or nasalization, is a process to convert a consonant into one of the nasal sound ㅁ(m) ㄴ(n) ㅇ(ng). When an ending consonant of a hangul is followed by a hangul with a beginning consonant ㅁ(m) or ㄴ(n), then nasal assimilation takes place. See the table below for the assimilation process.
